Presentation on Solar System for primary level students. Solar system is the collection of eight planets and their moons in orbit round the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.

1. Solar System

2. The Sun
• The Scientific name is Sol.
• It contains about 98% of all the rocks,
dust, and gas in the Solar System.
• If hollow, one million Earths could fit
inside.
• It acts as a giant magnet.
• The Sun’s surface is 6,000 degrees celcius,
but it’s atmosphere is millions of degrees.

3. Mercury
• It takes 87,969 days for Mercury to orbit the Sun
one time.
• Since it is smaller than Earth, it has less gravity
which means if you weighed 70 pounds on Earth,
you would weigh 27 pounds on Mercury.
• Mercury is so hot that you could burn to death
during the day, but spins so slowly that you could
freeze to death at night.
• It has no moons.
• There is almost no air on Mercury.
• It is 36 million miles away from the Sun

4. Venus
• It takes 224,701 days to orbit the Sun.
• You would way 63 pounds here if you
weighed 70 pounds on Earth.
• It is similar to Earth because it has
mountains, venusquakes, mountains and
valleys. You can’t live here though
because it is way too hot.
• It is 67 million miles away from the Sun.
• Venus has no moons.

5. Earth
• It takes Earth 365.3 days to orbit the Sun.
• We are 93 million miles away from the Sun
• It contains the only human life we know of.
• Earth has one moon, Luna.
• Earth has just the perfect combination of
weather, temperature, and atmosphere to
keep us alive.

6. Mars
• It takes 686.98 days to orbit the Sun.
• Mars is 142 million miles away from the Sun.
• Weighing 70 pounds on Earth, you would weigh
27 on Mars.
• Scientists have found that Mars once had streams,
rivers, lakes, and an ocean.
• Mars has two moons, Deimos and Phobos.
• Mars has the highest mountains and deepest
canyons in the whole Solar System. The largest
canyon on Mars would stretch from New York to
California here on Earth.

7. Jupiter
• It takes Jupiter 4332.59 days to complete one orbit around the
Sun.
• It is 482 million miles away from the Sun.
• You would weight 185 pounds on Jupiter if you weighed 70
pounds on Earth.
• Jupiter has a great red spot that is made up of storms that
have been constantly occurring for over 300 years.
• There is no solid surface here, it is just one huge ocean of
Hydrogen and Water. There is nothing in between the
atmosphere and the ocean, there would be no flat surface to
float a boat on like on Earth.
• Jupiter has 63 moons.
• It only takes 10 hours to go from night to day here.

8. Saturn
• It takes 10,759.2 days to orbit the Sun.
• You would weigh 82 pounds here if you
weighed 70 pounds on Earth.
• It’s rings are 169,800 miles wide, but less
thick than a football field.
• Saturn is very similar to Jupiter because
under it’s atmosphere is an ocean of liquid
chemicals.
• Saturn has 34 moons.
• It is 888 million miles away from the Sun.

9. Uranus
• It takes 30,684 days for Uranus to orbit the Sun.
• It is 1, 784 million miles away from the Sun.
• You would weigh 82 pounds here, if you weighed
70 pounds on Earth.
• It is the only planet that spins on it’s side.
• Uranus could have ocean under it’s atmosphere,
and because of the amount of pressure on Uranus,
it could possible have trillions of large diamonds.
• It is almost identical to Neptune.
• It has 27 moons.

10. Neptune
• It takes 60,190 days to orbit the Sun.
• Neptune has a giant storm just like Jupiter, it
is called the Great Dark Spot.
• It was discovered in 1846.
• It has 6 rings that surround it.
• Since Neptune is so far away, scientists know
of 13 moons for sure, but there could be
many more to be discovered.
• It is 2,794 million miles away from the Sun.
